I don't really need any switches just basically a box that will allow the signal to pass through and split in two directions for the sake of easy routing..... i have loopers to handle that stuff on the other end

You should be able to use this in A+B mix mode, using Send A and Send B as your two outputs. I think (but don't quote me on this), if you plug your tuner into the regular output when the LS-2 is bypassed you should be able to silently tune.

Also, the Boss is carried by almost every music store, so you shouldn't have trouble finding one, or returning it if it's not for you.
